Deactivate ssl validation on monitoring output

Hello,

due to a creation error in the Keys for the Elasticsearch HTTP SSL, i must deactivate ssl_certificate validation on all clients that are connecting to elasticsearch directly.

At the moment i can not recreate the keys due to uptime need.

The problem is i haven't found a configuration option to deactivate the certificate validation on the monitoring output of logstash version 6.8.1.

Has someone found a config for this or is there none? (and i must live with no monitoring data from Logstash until my next permitted longer downtime for the whole stack).

anyone know of such an option?
